• Temperature is the last temperature reading in “Temperature: X.X °C” format or
“Temperature: X.X °F” format, depending on the temperature units selected in the
setup dialog box.
• Sample time is the time of the start of the last reading in the selected Time format.
• Trend is the TOC trend over the last hour in “Trend: +/-X.X ppb/hr” format.
• Curve type is the curve type for the last TOC reading in “Curve Type: X” format, where
X can be one of four types (1, 2, 3, or 5). Curve types 1, 2 and 3 characterize the
conductivity profile over time during oxidation and indicate typical water chemistry.
Abrupt changes in the curve type can indicate a change in water chemistry. A 5 curve
type is a change in conductivity indicative of the possible presence of organic acid.
When a 5 curve type is experienced, the analyzer provides a Warning for possible
organic acids.
Date and time (top of screen) displays the current date and time in ISO format. Depending on
the current time format setting, the date and time is in 24-hour format (yyyy-mm-dd hh:mm:ss)
or 12-hour format (yyyy-mm-dd hh:mm:ss AM/PM). The date and time are configured in the
setup dialog box. The date display depends upon language selection.
Bottles icon (lower left corner of screen) displays the current state of the bottles in the bottle
bay. There are three states for this indicator (no bottles loaded, bottles loaded, or bottles
empty). Touching the icon takes you to the bottle mode dialog box.
Status indicator (lower right corner of screen) displays the status of the two UV lamps.
• Green indicates the UV lamp is good.
• Yellow indicates the UV lamp is marginal and should be replaced.
• Red indicates the UV lamp has failed and must be replaced.
Process animation (right side of screen) displays the current state of the analysis as an
animated graphic. There are five possible states: water flowing through the cell, water not
flowing through the cell, analyzing, new alarm condition, and acknowledged alarm condition.
Analysis results are displayed until a new analysis is complete. The values for conductivity,
temperature and time are the initial readings prior to the oxidation of the water sample.
